Ok I finally got around to making a tutorialThis is for moding a U360 for either topfire or LED BalltopPlease note that you must use a U360 restrictor for this to work (which I think just about everybody is cause the throw is just to long without one) I'm using the circular restrictor here

Here are the parts you need for the shaft partI used a 2.5mm threaded stereo jack, a *U360 shaft that has beed drilled out for the wire and the bottom section even further drilled out and tapped to accommodate the jack, you could use a a straight jack, but then you have to glue it in, and find a way to attach the E-Clipnext is the balltop drilled out for either an LED or for the topfire button, here I've used a button from radio shack , or an LED with the top and rim sanded off, and of course the wire (do not use solid core wire for this, I had that fail from twisting the wire into the shaft)*The shaft pictured is completely fabricated from scratch by Franco (Thanks again Buddy!) and has a wider thread at the top, so the balltop must be rethreaded tooI have done this with a stock U360 shaft but it is tougher to drill out the smaller thread at the top

Here is the finished Topfire shaft put together. You can see the jack isn't entierly screwed in to leave room for the E-Clip, I used a little lock-tite to keep it secure, I'm not showing the LED from here on out as the steps are exactly the same, except you might need a resistor on the other end

here the U360 magnet/cup with the magnet fitting perfectly inside the cup (no need to glue just let the magnet attach itself to the other one)

This is the 2.5mm stereo plug I used notice the the bottom is flat, this is important so the U360 magnet/cup sits flush against the bottom

the plug and a second 8mm x 2.5mm magnet

the plug wired and the magnet hot glued in (sorry it's not pretty, buy you get the idea)IMPORTANT: before glueing the magnet in make sure the the orientation is correct so that is is attracted to the U360 magnet/cupAlso notice I have 3 layers of heat shrink over the wires, I wanted this to be pretty tough cause it will hit the brackets when the joystick spins

You could skip the 2 magnets I added and just glue the U360 magnet to the plug, just make sure it's perfectly centeredHere you can see the finished shaft and plug connected in relation to an original U360Notice the difference in length, we now have to adjust for that, on to Step 3

Ditto here - I don't have the skills for this (or the equipment - I'm a hand tools guy) - I too would be willing to purchase a ready made or at least the custom components, like the shaft and the ball (assembly I can handle - i think). PM me.

This is excellent! Where did you get the top fire button from? I've recently made my own top fire button in a 35mm ball top for Seimitsu LS-32 using a hollowed out shaft from Arcadeshop.de. But I really struggled to find a decent button for the top fire. Nothing seemed to be just right and I ended up with a button that seems a bit weedy. But it does work perfectly. Your button looks perfect though.

I got that one from radio shack, they come in black too, the trick was threading the balltop, it has an odd thread count, 27 by something I thinkI bought a tap special just for that f#%@ing buttonYou can just make a hole and glue it in though

I've done pretty much the exact thing as your LED tutorial, however ... I'm curious about the Rotary. I know you have a Rotary tut coming, but have you had any success with a Rotary & LED (or pushbutton)?
